BEATING ENGINE.

Application filed October 23,

My invention relates to improvements in atmg en ines, and isparticularly conimprovements in beating enginesof the continuouslyoperating type.

The objects of my invention are,

First: To provide a beating engine of the type described having acapacity for protiming the maximum quantity of pulp or stock per unit oftime;

Second: To provide a beater of the type described comprising means forcontinuously and selectively withdrawing the finished pulp from thebeating-engine, and

Finally To rovidea beating engine of the character d escribed which issimple in construction, easy to operate, reliable, and economical tomanufacture.

Other objects of my invention will appear as this descriptionprogresses, reference bein had to the accompanying drawings, in Whi5l-Figure 1 is a mg engine; 4 I

Figure 2 is a longitudinal section therethrough, and

Figure 3 is a fragmentary view, partially in section, cwingcertaindetails of construction'on an enlarged scal Throughout the severalviews, similar reference characters will be used for referring tosimilar parts. i

Referring to the drawings,I 'haveillustrated my invention as forming apart of a beating engine comprising the conventional tank 5 7 having thebeating ,roll 6 and preferably. provided 7 of considerable height as toinsure comparatively plan of my improved beatwitha back fall :fomedtherein so rapid circulation of the contents of the tank.

The featherboard 8 of my improved heating engine may beof any desiredconstruction, except as the end portions thereof are modified in amannerdescribed lateron. In the present case, I have illustrated thein-' termediate portions of the. featherboard as comprising two spacedwalls or partitions 9, which are held in spaced relation by suitablespacers 10- The end portions of the two end walls-9, which pro ectbeyond the spacers or partitions 10, are joined 'to-- gether at theirlower portions by rounded walls 11, which form .s'tufi boxescommunieating with the dischar pipes 12 passing through the bottom oft ebeating engine.

1922. Serial No. 596,272.

-For the purpose of removing thefinished pulp or stock from the beatingengine, I. A

vide a pluralit naled in suitable bearing strips 14 and 15, and whichform continuations of the end portions of the walls 9. The bearingstrips 14 and 15 are bent in the form of loops so that the rollers ateach end of the featherboard form a chambercommunicating with the stulfboxes for receiving the finished pulp from the beating engine;

It will be noticed from an inspection of Figure '1 thatthe chambersformed by the the rounded vertical' rollers project into ends of thetank 5 ast the centers of the radii of these roun ed ends, so that thepro of vertically extending ori'zontally space rollers 13 which arejourvelocity of the contents of the tank is induced to a sufficientstate of fineness will pass out of the beatin engine through the spacesbetween the ro ers 13.

While I have discovered that rollers such as I have herein described aremost satisfactory for the purpose for which they are used, it is to beclearly understood that these elements need not be rotated but maysimply be rods spaced apart sulficiently to permit the finished pulp tobe beating engine.-

It should also be understood that where as I have disclosed a dischargechamber at each end of the featherboard, such construction is notnecessary, a chamber at one end of the featherboard being suflicient forsome purposes. Furthermore, it will be obvious that the rollers can belocated in one of the external walls of the tank as well as in thecentral wall or partition 9.

While I have described the details of con struction of the preferredembodiment of my invention, it is to be clearl gnnderstood that myinvention is not limi to these dedischarged from the tails ofconstruction, but is capable of other adaptations and modificationswithin the sco e of the appended claims.

aving thus described my invention, what I claim is: j

1. The combination of a beating engine including a tank, a featherboardand a beating roll, of means for removing the, fin ished pulp from saidtank comprising a plurality of vertical horizontally spaced rollersarranged to form a chamber at each end of. said featherboard, and anoutlet pipe connected with the lower end of each chamber.

2. The combination of a beating engine including a tank, a featherboardand a. beatroll, of means for removing the finished in P5P from saidtank comprising a plurality of vertical horizontally spaced rollersarranged to form a chamber at one end of said 'featherboard, and anoutet pipe connected with said chamber.

3. The combination of a beating engine including a tank, a featherboardand a heating roll, of means for removing the finished pulp from saidtank comprising a plurality of vertical horizontally spaced rodsarranged to form a chamber at one end of said featherboard, and anoutlet pipe connected with said chamber.

4. The combination of a beating engine including a tank, a featherboardand a beatin roll, of means for removing the finished pu p from saidtank comprising a plurality of vertical horizontally spaced rodsarranged to form a chamber at one end of said featherboard. I

v 5. The combination with a beating engine comprising a tank, a beatingroll, and means for causing rapid circulation of the contents of saidtank, of means for removing the finished pulp from said tankcomprising aplurality of vertical horizontally spaced rollers arranged'to form achamber extending below the Water line of said tank, and

The combination withabeating engine comprising a tank and a-beating roll, of means forremoving the finished pulp from said tank'comprising a plurality ofvertical horizontally spaced rods arranged to form a chamber extendingbelow the water line of said tank, and an outlet pipe connected withsaid chamber.

7. The combination with a beating engine comprising a tank and a beatingroll, of means for removing the finished pulp from said tank comprisinga plurality of spaced rods arranged to form the vertical walls of achamber extending below the water line of said tank, and an outlet pipeconnected with said chamber.

8. A. beating engine comprising a. tank,

one wall of which comprises a plurality of vertically spaced rollersextending below the water line.

- 9. A beatingengine comprising a tank one wall of which comprises aplurality o' movable elements arranged to form a plurality of elongatedslots lyingbelow the water line.

10. A beating engine comprising a'tank, one wall of which comprises aplurality of rotatable elements arranged'to form a plur'ality ofelongated slots lying. below the water line.

11. A beating engine comprising atank, a featherboard in said tankhaving a chamber formed therein, and means for continuously removingfinished pulp from said tank and discharge it into said chamber.

12. A beating engine comprising a featherboard having a chamber thereinforfeatherboard having a chamber therein for receiving the finished pulpformed by said engine, and means for continuously conducting thefinished pulp away from said chamber. i

14. In a beating engine, thecombination of a tank, a mid-feather in saidtank defining. a closed path therein for the flow of pulp, a beatingroll in said tank, and vertically pivoted rotatable discharge means atone end of said mid-feather and in continuation thereof for continuouslydischarging the pulp from said tank.
